Comment Out Matlab Mac Crack
Sibyl Piccuillo
Reason for this is, I have to try two different versions of a line and I don't want to replicate the line twice. I know it is easy to comment/uncomment if I replicate the line , But I want it this way.
When you write code, it is a good practice to add comments that describe the code. Comments allow others to understand your code and can refresh your memory when you return to it later. During code development and testing, you also can use comments to comment out any code that does not need to run.
To comment out multiple lines of code, use the block comment operators, % and %. The % and % operators must appear alone on the lines that immediately precede and follow the block of help text. Do not include any other text on these lines.
To comment out a selection, select the lines of code, go to the Editor or Live Editor tab, and in the Code section, click the comment button . You also can type Ctrl+R. To uncomment the selected lines code, click the uncomment button or type Ctrl+Shift+R. On macOS systems, use Command+/ to comment and Command+Option+/ to uncomment. On Linux systems, use Ctrl+/ to comment and Ctrl+Shift+/ to uncomment.
The Editor and Live Editor include tools and context menu items to help you add, remove, or change the format of comments for MATLAB, Java, and C/C++ code. For example, suppose that you have this lengthy text into a commented line.% This is a code file that has a comment that is a little more than 75 columns wide.disp('Hello, world')With the cursor on the line, go to Editor or Live Editor tab, and in the Code section, click the wrap comments button . The comment wraps to the next line:% This is a code file that has a comment that is a little more than 75% columns wide.disp('Hello, world')
My recommendation would be to use the package matlab-prettifier, which is based on listings but provides enhanced features for MATLAB code above and beyond those provided by listings' Matlab language definition (including support for block comments):
Here, [s] signifies that we are looking for two delimiters, the first to open a block comment and the second to close it. The following brace groups contain the opening and closing delimiters for a block comment, respectively. Note that both the percent sign and the individual open/close braces must be escaped by backslashes when defining the comment delimiters.
MATLAB also supports multi-line comments, akin to /* ... */ in languages like C or C++, via the % and % delimiters. But there is a small and important difference. In MATLAB it is not allowed that the lines starting with % or % contains any other text (except white spaces). Otherwise it would not work. E.g.
It is common and highly recommended to include as the first lines of text a block of comments explaining what an M file does and how to use it. MATLAB will output the comments leading up to the function definition or the first block of comments inside a function definition when you type:
Comments can also be used to identify authors, references, licenses, and so on. Such text is often found at the end of an M file though also can be found at the beginning. Finally, comments can be used to aid in debugging, as explained in Debugging M Files.
Single-line comments are comments that require only one line. They are usually drafted to explain what a single line of code does or what it is supposed to produce so that it can help someone to refer to the source code. Use % operator for adding single-line comments. This can be written in a separate line or appended to code on the same line.
1. Block comment is used in MATLAB if we want to prevent a particular block of code from getting executed
2. This is usually done to provide the explanation of the code without interfering with the compiler
3. There are various ways in which we can comment a block of code in MATLAB
When publishing your MATLAB code files (.m), you can enhance the readability of the published documents by adding markup to the comments within the files. Adding markup allows you to format the published documents and display external files and graphics.
Code sections allow you to organize, add comments, and execute portions of your code. Code sections begin with double percent signs (%%) followed by an optional section title. The section title displays as a top-level heading (h1 in HTML), using a larger, bold font.
You can add comments in the lines immediately following the title. However, if you want an overall document title, you cannot add any MATLAB code before the start of the next section (a line starting with %%).
You can mark selected text in the MATLAB comments so that they display in italic, bold, or monospaced text when you publish the file. Simply surround the text with _, *, or for italic, bold, or monospaced text, respectively.
Preformatted text appears in monospace font, maintains white space, and does not wrap long lines. Two spaces must appear between the comment symbol and the text of the first line of the preformatted text.
To indicate sample code, you must put three spaces between the comment symbol and the start of the first line of code. For example, clicking the Code button on the Publish tab inserts the following sample code in your Editor.
MATLAB enables you to insert LaTeX symbols in blocks that are offset from the main comment text. Two dollar sign characters ($$) on each side of an equation denote a block LaTeX equation. Publishing equations in separate blocks requires a blank line in between blocks.
You can insert static hyperlinks within a MATLAB comment, and then publish the file to HTML, XML, or Microsoft Word. When specifying a static hyperlink to a web location, include a complete URL within the code. This is useful when you want to point the reader to a web location. You can display or hide the URL in the published text. Consider excluding the URL, when you are confident that readers are viewing your output online and can click the hyperlink.
You can insert dynamic hyperlinks, which MATLAB evaluates at the time a reader clicks that link. Dynamic hyperlinks enable you to point the reader to MATLAB code or documentation, or enable the reader to run code. You implement these links using matlab: syntax. If the code that follows the matlab: declaration has spaces in it, replace them with %20.
Dynamic Link to Run Code. You can specify a dynamic hyperlink to run code when a user clicks the hyperlink. For example, this matlab: syntax creates hyperlinks in the output, which when clicked either enable or disable recycling:
Dynamic Link to a File. You can specify a link to a file that you know is in the matlabroot of your reader. You do not need to know where each reader installed MATLAB. For example, link to the function code for publish.
Dynamic Link to a MATLAB Function Reference Page. You can specify a link to a MATLAB function reference page using matlab: syntax. For example, suppose that your reader has MATLAB installed and running. Provide a link to the publish reference page.
imwrite(___,Name,Value) specifies additional parameters for output GIF, HDF, JPEG, PBM, PGM, PNG, PPM, and TIFF files, using one or more name-value arguments. For example, you can add a comment to an image in PNG format.
Comment to add to the image, specified as a string scalar, a character vector, an n-by-1 string array, or an n-by-1 cell array of character vectors. For a string array or cell array of character vectors, imwrite writes each row of input as a comment in the JPEG file.
Comment to add to the image, specified as a string scalar, a character vector, a string array, or a cell array of character vectors. For a string array or cell array of character vectors, imwrite writes each entry as a comment in the JPEG 2000 file, in column-major order.
Adding Comments in M-FilesComments in an M-file are strings or statements that do not execute. Add comments in an M-file to describe the code or how to use it. Comments determine what text displays when you run help for a filename. Use comments when testing your files or looking for errors--temporarily turn lines of code into comments to see how the M-file runs without those lines. These topics provide details:
To uncomment the current line or a selected group of lines, select Uncomment from the Text menu, or right-click and select it from the context menu. Comment to make those lines become comments in the M-file. -->
